The floating Wind turbines off-load method controlled based on TMD and active anchor chain structure

The invention discloses a kind of floating Wind turbines off-load method controlled based on TMD and active anchor chain structure, one) it is in stretched wire state in anchor chain：1) equation of motion of floating platform, pylon and TMD damper force and piston are obtained relative to the correspondence between the displacement of cylinder body by analysis, 2) are established respectively；Two) it is in tensioning state in anchor chain：1) active control establish the dependent dynamics equation of floating platform and anchor chain, 2) is carried out to the motor for controlling anchor chain, to shrink and discharge the anchor chain of connection floating platform, so as to which floating platform be made to reduce surging, the phenomenon that swaying and yawing.While the present invention is adjusted by using passive TMD, and change stretched wire state for different sea situations, the load response of the floatation type Wind turbine of seagoing barge formula structure is controlled, so as to effectively reduce the pitching movement of General load and cabin, floating platform of the floating wind energy conversion system under different operating modes, and then improve the output power quality of floatation type Wind turbines and increase its service life.
